<u>Answer</u>
A) 40°
<u>Explanation</u>
Assuming that the angles are measured from the center, we can use the properties of a circle to find <CAE.
Angles subtended by at the center by the same arc double the angle at the circumference.

Volume of a Cylinder:
V = pi * r^2 * h
Plug in what we know:
V = 3.14 * 0.5^2 * 5
V = 3.925
Now we divide 3.925 / 0.48 to find out how many batches of mortar we can make with one cylinder of sand.
3.925 / 0.48 = 8
So he can make 8 batches of mortar.
You just take 1000 and multiply it by .05. Its 50mL.
Answer:
Step-by-step explanation:
To solve using completing square, we need to write the equation as x2+3x=17.
The next step is to add a number such that the square can be completed. The number must be equal to (b/2a)^2, so here it will be (3/2)^2 = 9/4
The equation then becomes x2+3x+(9/4)=17+(9/4).
Solving it further will get you the final answer
